TCONtrol <name>
[:SENSe[1]]:AVERage:TCONtrol <name> Set average filter type
:SENSe2:AVERage:TCONtrol <name> Set average filter type
Parameters <name> = MOVing Moving average filter
REPeat Repeat average filter
Query :TCONtrol? Query type of average filter
Description These commands are used to control the type of average filter. The
REPeat filter places the specified number of measurement conversions
into a stack and averages them to yield a single repeat filter reading. The
stack is then cleared, and the process starts over.
The MOVing average filter uses a first-in, first-out stack. When the stack
(filter count) becomes full, the readings are averaged, yielding a filtered
reading. For each subsequent reading placed into the stack, the oldest
reading is discarded. The stack is reaveraged, yielding a new reading.
ADVanced:NTOLerance <n>
[:SENSe[1]]:AVERage:ADVanced:NTOLerance <n> Set filter noise window
:SENSe2:AVERage:ADVanced:NTOLerance <n> Set filter noise window
Parameters <n> = 0 to 105 Specify filter noise tolerance in %
DEfault 5
MINimum 0
MAXimum 100
Query :NTOLerance? Query filter noise tolerance value
Description When the advanced filter is enabled (see “STATe” below) a noise win-
dow is used with the average filter. This command is used to specify the
noise window. If readings are within the noise window, the average filter
operates normally. If, however, a reading falls outside the window, the
buffer is flushed of old readings and filled with the new reading.
ADVanced[:STATe] <b>
[:SENSe[1]]:AVERage:ADVanced[:STATe] <b> Enable/disable advanced filter
:SENSe2:AVERage:ADVanced[:STATe] <b> Enable/disable advanced filter
Parameters <b> = 0 or OFF Disable advanced filter
1 or ON Enable advanced filter
Query [:STATe]? Query state of advanced filter
Description This command is used to enable or disable the advanced filter. When
enabled, the noise window is used with the averaging filter. When dis-
abled, the noise window is not used.
